Specification of Letters Patent. Patented Feb. 28, 1922.

Application filed November 8, 1920. Serial No. 422,453.

To all whom it may concern:

My invention relates to improvements in work bench Vises in which a removable jaw anchored to a base mounted upon a screw is caused to advance or retreat by the operation of the screw, thereby creating a relation between the removable jaw of such base and a corresponding jaw anchored in alignment therewithby plate means in the surfaceof the work bench, in such manner as to provide means-of holding material being worked, upon between such jaws securely during the work. The object being to provide removable jaws variably stationed apart of size suitable to" the varying thickness and length of the material being worked upon; and the work desired and to provide removable jaws which grasp uniiormly, remainstable and which maybe changed quickly and of varying sizes suitable to the 'work; and to provide means in the combined base and jaw construction of relieving the screw. ofthe-vise from the strain of the clamp or the strainof the pressure exerted upon the article worked upon; and to provide a removable jaw and base so suited to each other as to prevent thejaw "from becoming displaced under the vibration createdby the work upon thearticle worked upon; and to provide a vise in which the screw maybe used at the end oi": the bench without increased protrusion; and to provide a visesuitable for use in large or small work yet of a size so diminutive that in attaching'it toany work bench not only does not interfere with the other uses to which the bench maybe put, butdoes not weaken the strength or mar the beauty of the work bench I r I attain these objects by the mechanism illustrated in the accompanying drawings, in whiohz. I

view I of a minor Similar letters refer to similar parts throughout the several views. I

The major plate 1 is composed of an oblong-flat plate 1, having one of its ends right-angularly square and flanged to a right angle 2, the other end rounded. In the center of major plate 1 I provide a right-angularly disposed oblong slot 1 extending from a point suitably near the flanged end 2 to a pointsuitably near the rounded end. The

oblong slot 1 having provided in the end nearest the rounded point of plate 1, a right: angular oblong oflset 1 0i size conformable to the neck 11 of stationary. clamp 11. In the rounded endof major plate 1, I provide suitable milled holes, counter sunk for the insertion of means suitable for securing to such end boxing brace 1,. and at the sides and ends of major plate 1 I provide multi- I ple holes 1 for the insertion of means for securing the same to the work bench..

The under side of said -major plate 1 is also provided at either sideiof the oblong slot 1 with right-angularly disposed flanges 8 which serve as a guide channel in which I the flanged top 9 of jaw base 9- travels whiohjaw base 9 is operated on screw 5 v and which flanges 3 extend toward the round point of plate 1,suitably longer than oblong slot 1 to admit the making of another oblong offset 1 in the plate lat the end of slot 1 for the clamp 11. V I 1 The flanged end 2 of major plate 1 partly covers a suitable shoulder boxingi2e stationed connectedly to the flanges 3 the edgesvof plate 1 and-flange 2 extending flangedlyqbeyond the shoulder boxing 2 the corner-of the shoulder boxing 2 'being cutaway suitably to permit the operation of boss 5 -of screw 5. 1

In the lower portion of the shoulder boxing 2 is provided a boxing hole extending purpose of inserting stationary 5, forming a boxing for the screw stem 5.

For operation I provide a screw having its point 5 and stem 5 journaled, and also having a boss 5* and a screw stem head, 6.,

provided with a suitable handle 8 mounted thereon, and secured thereto by screw means 7, said screw 5 being for-the purpose of operating the jaw clamp traveling base 9, and the threads thereof conformable to the threads 9 thereof. a At the point end and on the under sid of major plate 1, I provide a boxingbrace 1 attaching flush against flanges 3 and secured t holes 1 1 In the bottom of boxing brace 4 I provide a boxing 4 for the insertion of journal point 5 of screw 5, said boxing 4 of boxing brace 4:, being in alignment with the hole provided in the flanged portion 2? cl" shouldei boxiiig 2, for the purpose of holding the screw 5 in lineal alignment with major plate 1, at all times.

I provide a jaw clamp traveling base 9 being an oblong square metallic block having centrally lineally disposed therein a threaded hole 9 suited to the size and threads of screw 5, and'intended to be mounted and to travelupon screw '5. The traveling base 9 is constructed with: a square flange '9FeXtending from'one of its sides ab'out half its length but flush with one of itsends cen-' trally disposed between two of its sides and of height corresponding to the combined breadth of flange 3 and the thickness of major plate '1, and o't width corresponding to the width of oblong slot 1 of the major plate 1, the intent being that the top of flange 9 shall whenbase 9 is mounted andtraveling,

belevel with the surface of majorplate 1,

and that the flange 9 fitting in slot 1 shall prevent base 9 from turning when screw 5 v inserted in hole 9 is turned, thus causing base 9 to travel forward or backward cor responding to the turn of'screw 5 therein. Flange 9" is centrally provided with a hole 9 disposed parallel to the threaded: hole--9 as ameans-for securing the movable jaw clamp 10 thereon.

I provide a movable jaw clamp lO for use in connection wi-tlrtraveling base 9 when mounted upon screw 5, andstationary clamp 11; which movable jaw clamp is composed of a metalic plate 10? having on one'side centrally disposed therein at right angles, a pinofsize comformable to hole 9 in flange 9 of base 9, and for insertion therein; the

met-alic plate having at one of its ends and at either edge flangedly disposed shoulders lO which taperupward-forminga bit, the bit having its edge directioned towardqthe side oppositeto thepi'n 10", the edge of the bit being provided-with multiple protrudplate 1 by any suitable means. in;

clamp 10 to take the ing teeth,10, the teeth protrudingsuitable to grasp the article worked upon. shoulders lOLarev also directioned rightangularly outward and backward with the pin and are so constructed as to slope down- The i resting flat upon the surface of major plate I 1 when mounted, pin 10 being positioned in plate 1, suitable sothat the distancebet ween pin 10 and head 10? will correspond to the" distance between the hole 9 and the top offlange 9 oftraveling base 9, the intent; be-

ing to form a brace of shoulders 9 and 9 of base 9, and the bottom of head 10 of jaw in operation.

I also" provide a stationary jawclamp 11, for'use in connection with major plate 1, and minor plates 12'which stationary jaw clamp 11 iscomposed of around metal button 11 of size conformable to hole 12 m minor plate 12 and not of greater diameter than thewidth ofslot 1 inmajor plate; 1, the button 11 having right angularly protrudin from one of its sides 'a rectangular oblong neck 11 of lengthequaling the thickness of major plate '1, and minor plate 12, the sides and edges of rectangular oblong strain off of screw 5V neck 11 being of dimensions conformable to the rectangular offset 1? in the point end of major plate 1, and to the rectangular offset 12 in minor plate 12. V The sides and one ofthe edges of neck 11 on the end opposite button '11 are' r-ightangularlyflanged shoulders, the other edge the full lengthof the shoulder flanges being faced upward to fornr an oblong serrated bit 11 havingmultiple teeth and of size conformableto the teeth of movable jaw clamp-10, the bottomof theshoulder flanges at the sides and edgeof neck 11 presenting broad flat surfacessuitable to cause them to lay flat upon thesurface of major plate 1 and minor plate 12 when mounted and to cause a bracing effect between them and the flange of the button 11 about neck 11*. The top of the shoulder-"flanges from the fser= ratedbit ll slopes bacl'rward to 'theline of the flange, the ends being rectangular. The

serrated bit 11 is directionedslightly-forward protruding somewhat from theper-M pendicular outward in order to grasp the article worked upon. Stationary jawclamp ismounted by inserting the button-and neck inhole 12 ofminorplatejlQ-or the slot 1 of major plate with; the serrated-,bit 11 "di? is desired to work upon articles longer than major plate 1. As many of them may be employed as is desired. In installation it is embedded in a groove formed in and so made level with the surface of the work bench, the groove in the work bench being formed deep enough to admit and conformable to allow the insertion of button 11 beneath the minor plate 12 in alignment with hole 12 and offset 12 of minorplate 12.

Minor plate 12 is a metallic right-angular plate provided at each of itscorners with construction hole means suitable for being secured to a work bench by screws or other suitable means, and it is centrally provided with a key hole 12* and 12 of size and shape of jaw clamp 11.
